==Introduction==
'''Induction''' of anaesthesia can be performed using either an [[Injectable Agents|injectable agent]] or an [[Inhalation Agents|inhalation agent]]. It is most commonly performed after a premedication has been administered and had time to take effect, but this is not always necessary. Endotracheal intubation also occurs at this stage after the animal has been induced and is an appropriate anaesthetic depth.

===Intravenous Catheterisation===
===Intravenous Catheterisation===
Most commonly a patient receives an induction agent that is given intravenously as this route often gives the quickest induction. Many patients will also be receiving [[Fluid Therapy|fluids]] during their procedure which will also require placement of a catheter. It is therefore recommended that an intravenous (IV) catheter is placed in all patients undergoing an anesthetic procedure. This also means that clinicans have intravenous access in the face of an emergency also. In small animal patients, a catheter is usually placed in the cephalic vein if it is not within the surgical field, or the saphaneous vein may be used. In horses, a jugular catheter is placed.
